Help Ada basics

Help Ada basics

[Ratson Janiv]

I have the following not compiling code:
============================================
generic

type Language is array (Positive range<>) of Character;

type States is array (Positive range <>) of Integer;


package Automat_Producer is


...

===========================================================

And also :

*************************************************************

with Automat_Producer;

generic

with package My_Automat is new Automat_Producer (<>);


procedure Apply_String(Auto: in My_Automat; S:String);

*******************************************************************

What M I doing wrong ?

Compiler error:

apply_string.ads:6:33: subtype mark required in this context

apply_string.ads:6:33: found "My_Automat" declared at line 4



10x,

J.

My_Automat is a package, not a subtype. The compiler message is quite
precise.

No one other than you can possibly know. We can tell you that what you 
wrote is illegal--heck the compiler did that.  We can give you hints as 
to how you might be able to say what you are trying to say.  But without 
the information which currently exists only in your head, no one else 
can tell you what the "right" syntax is without a lot more information 
than you have supplied.

Go find a TA, instructor, or even someone you know who knows Ada, and 
see if they can help get your thinking straightened out.  From 
experience that is a very tough job without being face to face.
